Turning to the spheroid wake, we find that its turbulence topology is different from that of the mean. In the region \(5 \le x \le 15\) , TKE shows two off-center peaks reminiscent of the TBL shedding from a slender body [1]}, [2]}, [3]}, [4]} while mean \(U_x\)  shows a single central peak. At \(x = 20\) , we see the start of a horizontal contraction of the mean velocity in the central region of the wake and the emergence of a `butterfly' shape reminiscent of the separation and wake patterns observed in [5]}, where the \(\mbox{\textit {Fr}}_c = 4/\pi \approx 1\)  wake of a 4:1 spheroid was studied. Note that in this stage, the wake is thinner than taller, i.e., \(L_H<L_V\) . At \(x \approx 20\) , TKE starts transitioning from a bimodal distribution to a single peak near the center-horizontal plane. In the next section, we will analyze how the horizontal contraction of the mean wake between \(x = 20\)  and \(x = 40\)  results in an increased horizontal mean shear, resulting in the maximum TKE being produced close to the center-horizontal plane. This leads to a transition in the TKE topology from bimodal distribution to a squeezed-Gaussian distribution at \(x \gtrsim 40\) . By \(x \approx 60\) , \(U\)  has been organized into two distinct layers while TKE is sustained between these two vertically off-center layers. Note that the multi-layered mean flow structure at late \(x\)  in the \(\mbox{\textit {Fr}}= 2\)  spheroid wake is reminiscent of the layered structure of the Q2D regime [6]}.
